Misha Calvin [real surname Nisic] is a Serbian rock guitarist and songwriter. A native of Yugoslavia, Calvin arrived in London sometime in the mid 80s. He worked with ex-Black Sabbath vocalist Tony Martin and Elegy vocalist Ian Parry, producing the album Evolution, released by Vienna Records in 1993.

Former Black Sabbath vocalist Tony Martin appeared on most of the album, and was in particularly fine voice on songs like ‘Strangers’, ‘Ready Or Not’, ‘Reaper’ and the big ballad ‘Put A Little Faith In Me’; former Vengeance (and current Elegy) frontman Ian Parry did a fine job on three other songs. Steve Dunning, now John Lawton’s bassist, and ex-Girl drummer Pete Barnacle were part of a talented supporting cast. The album received acclaim from the melodic hard rock community.
